Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Why do we use it?

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

Where does it come from?‍

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.

The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.

Warm compartments, clicking relays, frost‑packed evaporators, or fan errors suggest airflow, control, or sealed‑system problems. Start with coil cleaning, airflow checks, and a hard reset. If temperatures don’t drop or codes persist, a pro should test fans, relays, defrost system, compressor start gear, or refrigerant levels to prevent food loss and compressor damage.

A refrigerator that is not cooling poses one of the most urgent appliance problems because it threatens food safety and creates immediate inconvenience. When the interior remains warm, groceries spoil quickly, and families may be forced to discard large amounts of food. Refrigeration systems are designed to maintain consistent cold temperatures by cycling refrigerant through compressors, evaporators, and condensers, regulated by fans and sensors. When any part of this chain fails, cooling performance drops or stops entirely. Sometimes the refrigerator may seem to run but not produce sufficient cold air, while in other cases it remains completely silent. Causes can range from simple issues like dirty condenser coils to serious failures such as compressor breakdowns. Control boards, thermostats, and sensors also play critical roles in regulating temperature, and their failure can shut down cooling entirely. Because cooling problems can escalate quickly, understanding the symptoms, potential causes, error codes, and repair paths is vital to restore reliable refrigeration before food loss becomes severe.

Landlord responsibility: In New York, landlords are legally obligated to maintain appliances they provide in a safe and working order. This is part of the "Warranty of Habitability".

The primary symptom of a refrigerator not cooling is elevated internal temperatures, often first noticed when milk spoils prematurely or ice cream softens. Users may hear the compressor running constantly without producing cold air, or they may find the refrigerator unusually quiet, indicating that the compressor is not engaging. Another symptom is warm air blowing inside the fresh food or freezer compartments when fans are running but cooling does not occur. Frost buildup on the evaporator coils can signal a defrost system failure, which prevents air from circulating properly. Water pooling beneath the refrigerator may result from thawing ice when cooling stops. Error codes may flash on digital models, pointing to sensor or compressor issues. Other signs include the refrigerator running longer than normal cycles, clicking sounds from relays attempting to start the compressor, or lights working while cooling functions remain inactive. Inconsistent cooling is also common, with some compartments colder than others. These symptoms collectively point toward interruptions in the refrigeration cycle or airflow system.

Qiuck Fixes

Some quick fixes can help restore refrigerator cooling. Cleaning condenser coils is one of the most effective steps, as dust buildup reduces efficiency. Ensuring that vents inside the refrigerator are not blocked by food allows airflow to circulate. Resetting the unit by unplugging it for several minutes can clear temporary board errors. Checking that the temperature controls are correctly set prevents user errors. Inspecting fans for obstructions or ice buildup can also restore circulation. In some cases, defrosting the unit manually for 24 hours clears ice-blocked evaporators. Ensuring the refrigerator is not overloaded and that doors seal properly also improves performance. These steps address user-level mistakes and minor airflow issues. However, they cannot resolve compressor failures, refrigerant leaks, or board malfunctions. If quick fixes do not restore cooling within a few hours, the problem likely requires professional repair. Users should avoid tampering with sealed systems or refrigerant lines, as this requires certification. Quick fixes provide reassurance but only solve surface-level issues.

Error Codes

Error codes for refrigerators not cooling vary by brand but generally highlight issues with cooling circuits, sensors, or fans. Samsung refrigerators often display codes like 22E or 22C for fan errors, 83E or 85E for compressor faults, and 88 for system resets. LG models may show ER FF for freezer fan failures, ER IF for ice fan issues, or ER CF for condenser fan problems. Whirlpool and Maytag units often display codes such as E1 for sensor errors or E2 for thermistor problems. GE refrigerators may use codes like FF for fan faults or 88 for communication errors. Electrolux and Frigidaire may display SY EF for evaporator fan failures or dH for defrost issues. Bosch units often use E01 or E02 for compressor or control faults. Across all brands, common codes indicate fan failures, thermistor errors, refrigerant system problems, or communication breakdowns. These codes direct technicians to inspect airflow, defrost systems, sensors, and compressors. For users, they highlight that the cooling process is compromised.

When to Call a Professional

Professional service is required when refrigerators remain warm despite coil cleaning, resets, and airflow checks. If error codes persist, or if fans and compressors fail to engage, technicians must test electrical circuits and sealed system pressures. Compressor failures, refrigerant leaks, and control board malfunctions are all repairs beyond user capability. Continuous clicking sounds, warm freezer temperatures, or repeated defrost issues all demand expert attention. Professionals use gauges to measure refrigerant, multimeters to test components, and OEM boards to restore control. For high-end or inverter-driven refrigerators, board replacements and firmware updates may be necessary. Ignoring persistent cooling problems risks food spoilage, water leaks, and compressor burnout. Prompt service ensures food safety, restores efficiency, and prevents costly replacement of the appliance.
